FLASHLIGHT.

Specification of Letters Patent.

Patented Nov. 29,1921.

Application led February 28, 1921. Serial No. 448,692.

To all whom t may concern:

Be it known that I, AnoLPH C. RECKER, a citizen of 'the United States,residing at Oakville, inthe county of Litchfield and State ofConnecticut, have invented a newv and useful Improvement in Flashlights;and I do hereby declare the following, when taken in connection with theaccompanying drawingsand the charactersof reference marked thereon, tobe a full, clear, and exact description of the same, and which s aiddrawings constitute part of this application, and represent, in

Fi re 1, a view in side elevation of a flash ight constructed inaccordance with my invention.

Fig. 2, an enlarged view thereof in central longitudinal section, withits telescopic cover in its normal or extended position in which thecircuit through the lamp is open. l

Fig. 3, a` corresponding view with the cover and cell telescoped toclose the circuit through the lamp.

My invention relates to an improved flashlight, the object being tomount` the lampcarrying means directly u on tl1e cell itself, and thusproduce a Simp e, light, compact, convenient and effective. lamp at thevery minimum expense.

With these ends 'in view, my invention consists in a flashlight havinglamp-carrying means telescopically mounted directly upon the cell itselMy invention further consists in certain details of construction andcombination of parts as will be hereinafter described and pointed out inthe claims.

In carrying out my invention as herein shown, employ lamp-carrying meansconsisting of a cylindrical sheet-metal cover I5 having its outeredgeturned inwardly to form a retaining-flange 6 conlining a lens 7, theinner edge of which lrests upon a reflector 8, having a concentricthreaded sleeve 9 receiving the threaded stem 10 of an incandescent lamp11 having a terminal 12. A rubber tube 13 encircling the threaded sleeveof the reflector engages at its outer end with the inner face of thereflector, so as to hold the same in position within the telescopiccover 5, while the inner end of the tube lits snugly over the projectingend of the carbon electrode 14 of the." cell and rests upon the seall orclosure 15'` thereof. The electrode .14 and closure 15 form features ofan ordinary dry' cell also comprising a zincv cup 16 and an electrolyte17, which latter surrounds the elect-rode 14 and is confined within thezinc cup by .the closure 15.

At its inner end the telescopic-cover 5 is formed with inwardlyprojecting circumferential assembly-threads 18, which coact withcorresponding but outwardly projecting assembly-threads 19, formed inand slightly offset from the edge of the cup 16.

The said threads 18 and 19 provide for mounting the cover 5 upon the cup16 and retaining it thereupon, while, at the same time, providing forthe telescopic movement of the cover and cell with respect to eachother. Normally the yrubber tube 13 exerts a constant outward pressureagainst the reliector 8, which in turn pushes outward upon the lens 7,which in'turn similarly acts upon the cover 5,V to hold the same in itsextended position, in which the innermost of the threads 19 in the cup16 of the cell coact with the outermost of the threads 18 in the cover 5to form a stop, preventing' the cover and cell from separating. To lightthe lamp the cover 5 is longitudinally compressed with suflicient forceto telescope it over the battery-cell 16, and so deform the tube 13suiiciently, as shown in Fig. 3, to permit the lam4 -terminal 12 to bebrought into contact with theadjacent end,v of the electrode 14 and soclose the circuit throu n 'the lamp. The contact thus established ependsupon the maintenance of such compression, so that the moment thatcompression is removed, the rubber tube 13' reas! serts itself'andpushes the cover outward 4into its normal or extended position, in

' opening positions,

my invention being characterized by a flashlight in which lampcarryingmeans are telescopically applied directly to a cell.

I clalm: 1. A flashlight means adapted to having its lamp-carrying berotatably applied and 1 thereafter telescopically mounted directly saidcup, the said cup and cover. having assembly-threads which engage withan pass by each other and act as a stop for the cover, a lamp carried bythe cover, and means for yieldingly maintaining the'cover in itsextended position in which the lam terminal is held out of contact withtg said electrode.

4.- A flashlight compri zinc cup and an electrode, a covertelescopically mounted directly upon 'the cup, the said cup and coverhaving assembly-threads adapted to pass by each other and to act as asto for the cover, a lamp and a reiector t erefor carried by the cover,and yielding means interposed between the re- Hector and cell fornormally maintainin the cover in its extended position and the imp andelectrode terminals out of contact.

In testimony whereof, l have signed this specification in the presenceof two subscribing witnesses.
